Sixth cranial nerve palsy is weakness of the nerve that innervates the lateral rectus muscle. The lateral rectus muscle rotates the eye away from the nose and when the lateral rectus muscle is weak, the eye crosses inward toward the nose ( esotropia ). The esotropia is larger when looking at a distant target and looking to same side as the affected lateral rectus muscle. Complete palsies with symmetrical atrophy of both compartments of the lateral rectus (Figure 6)are the most straightforward to diagnose because of the accompanying large esotropia and severely restricted abduction.
